COMP: Adjust fuzzy compare tolerance
COMP: Adjust fuzzy compare tolerance

Regarding UnitTestFunctionParser...

Dan Lisa reports "We been having failures for this test on amber12
when compiling in Release mode. Debug mode works OK.  Intel processors
have internal 80 bit floating point registers and can do floating
point calculations using those. Using those registers, which happens
when enabling optimizations will yield different results than doing
computation using 64bit floats."

Inspection of the failures shows that the FuzzyCompare tolerance needs
to be adjusted. Using a factor of 128 * epsilon should resolve the
failures while maintaining a high level of accuracy for the
comparison.
